Seat Precautions
WA R N I N G
Make sure the adjustable components of a seat are locked in place:
Adjustable seats and seatbacks that are not securely locked are dangerous. In a sudden stop
or collision, the seat or seatback could move, causing injury. Make sure the adjustable
components of the seat are locked in place by attempting to slide the seat forward and
backward and rocking the seatback.
Never allow children to adjust a seat:
Allowing children to adjust a seat is dangerous as it could result in serious injury if a child's
hands or feet become caught in the seat.
Do not drive with the seatback unlocked:
All of the seatbacks play an important role in your protection in a vehicle. Leaving the
seatback unlocked is dangerous as it can a llow passengers to be ejected or thrown around
and baggage to strike occupants in a sudden stop or collision, resulting in severe injury. After
adjusting the seatback at any time, even when there are no other passengers, rock the
seatback to make sure it is locked in place.
Adjust a seat only when the vehicle is stopped:
If the seat is adjusted while the vehicle is being driven, the seating posture may become
unstable and the seat could move unexpectedly resulting in injury.
Do not modify or replace the front seats:
Modifying or replacing the front seats such as replacing the upholstery or loosening any bolts
is dangerous. The front seats contain air bag components essential to the supplemental
restraint system. Such modifications could damage the supplemental restraint system and
result in serious injury. Consult an Authorized Mazda Dealer if there is any need to remove or
reinstall the front seats.
Do not drive with damaged front seats:
Driving with damaged front seats, such as se at cushions torn or damaged down to the
urethane, is dangerous. A collision, even one no t strong enough to inflate the air bags, could
damage the front seats which contain essential air bag components. If there was a
subsequent collision, an air bag may not deploy which could lead to injuries. Always have an
Authorized Mazda Dealer inspect the front seats, front seat belt pretensioners and air bags
after a collision.

Do not drive with either front seats reclined:
Sitting in a reclined position while the vehicle is moving is dangerous because you do not get
the full protection from seat belts. During sudden braking or a collision, you can slide under
the lap belt and suffer serious internal injuri es. For maximum protection, sit well back and
upright.
Do not place an object such as a cushion between the seatback and your back:
Putting an object such as a cushion between the seatback and your back is dangerous
because you will be unable to maintain a safe driving posture and the seat belt cannot
function at its full capacity in a collision, wh ich could result in a serious accident, injury or
death.
Do not place objects under the seat:
The object could get stuck and cause the seat to not be fixed securely, and result in an
accident.
Do not stack cargo higher than the seatbacks:
Stacking luggage or other cargo higher than the seatbacks is dangerous. During sudden
braking or a collision, objects can fly around and become projectiles that may hit and injure
passengers.
Make sure luggage and cargo is secured before driving:
Not securing cargo while driving is dangerous as it could move or be crushed during sudden
braking or a collision and cause injury.
Never allow a passenger to sit or stand on the folded seatback while the vehicle is moving:
Driving with a passenger on the folded seatback is dangerous. Allowing a child to sit up on
the folded seatback while the vehicle is moving is particularly dangerous. In a sudden stop or
even a minor collision, a child not in a proper seat or child-restraint system and seat belt could
be thrown forward, back or even out of the vehi cle resulting in serious injuries or death. The
child in the baggage area could be thrown into other occupants and cause serious injury.
CAUTION
 When operating a seat, be careful not to put yo ur hands or fingers near the moving parts of
the seat or on the side trim to prevent injury.
 When moving the seats, make sure there is no cargo in the surrounding area. If the cargo
gets caught it could damage the cargo.

When moving the seats forward and rearward or returning a rear-reclined seatback to its
upright position, make sure you hold onto the seatback with your hand while operating. If
the seatback is not held, the seat will move suddenly and could cause injury.
 When inserting your hand under the seat to clean the cabin or pick up something you
dropped under the seat, be careful not to hurt yourself. If you contact the moving parts of
the seat rail or seat frame, it could result in injury.
NOTE
When returning a rear seat to its original position, place the seat belt in its normal
position. Verify that the seat belt pulls out and retracts.
(Power Seat)
The seat-bottom power adjustment is operated by motors. Avoid extended operation
because excessive use can damage the motors.
To prevent the battery from running down, avoid using the power adjustment when the
engine is stopped. The adjuster uses a large amount of electrical power.
Do not use the switch to make more than one adjustment at a time.
When getting in and out of the vehicle, your foot could accidentally contact the seat height
adjustment lever and cause the seat to lower.
Adjust the seat to obtain the correct driving position.

Rear Seat
▼Split Folding the Seatbacks
By lowering the rear seatbacks the luggage
compartment space can be expanded.
WA R N I N G
Do not drive the vehicle with occupants on
folded down seatbacks or in the luggage
compartment.
Putting occupants in the luggage
compartment is dangerous because seat
belts cannot be fastened which could lead
to serious injury or death during sudden
braking or a collision.
Do not allow children to play inside the
vehicle with the seatbacks lowered.
Allowing children to play in the vehicle
with the seatbacks folded down is
dangerous. If a child enters the luggage
compartment and the seatbacks were
raised back up, the child may become
trapped in the luggage compartment
which could lead to an accident.
Tightly secure cargo in the luggage
compartment when it is transported with
the seatbacks folded down.
Driving without tightly securing cargo and
luggage is dangerous as it could move and
become an obstruction to driving during
emergency braking or
a collision resulting
in an unexpected accident.
When transporting cargo, do not allow the
cargo to exceed the height of the
seatbacks.
Transporting cargo stacked higher than
the seatbacks is dangerous as visibility to
the rear and sides of the vehicle is reduced
which could interfere with driving
operations and lead to an accident.
Lowering the seatbacks
CAUTION
 When folding the seatback forward,
always support the seatback with your
hand. If it is not supported by a hand,
fingers or the hand pressing the push
knob could be injured.
 Check the position of a front seat before
folding a rear seatback.
Depending on the position of a front
seat, it may not be possible to fold a rear
seatback all the way down because it
may hit the seatback of the front seat
which could scratch or damage the front
seat or its pocket. Remove the head
restraint on the rear outboard seat if
necessary.
 (Vehicles with rear armrest)
Before folding a rear seatback, make sure
that the armrest is stored. If a seatback is
lowered without storing the armrest, it
could deform, damage, or scratch the
armrest.
1. Lower the head restraint all the way down.
Refer to Head Restraints on page
2-17.

To return the seatback to its upright
position:
WARNING
When returning a seatback to its upright
position, make sure the 3-point seat belt is
not caught in the seatback and the 3-point
seat belt is not twisted.
If the seat belt is used while it is twisted and
caught in the seatback, the seat belt
cannot function at its full capacity, which
could cause serious injury or death.
When returning a seatback to its upright
position, make sure that it is firmly locked
and the red indication is not visible.
If the red indication is visible behind the
push knob, it means the seatback is not
locked. If the vehicle is driven without the
seatback locked, it could fold down
suddenly and cause an accident.

▼Armrest*
The rear armrest in the center of the rear
seatback can be used (no occupant in the
center seat) or placed upright.

WA R N I N G
Never position the shoulder portion of a
seat belt over the armrest:
Positioning the shoulder portion of a rear
seat belt over the armrest is dangerous as it
cannot provide adequate protection in a
collision and could result in serious injuries.
Never put your hands and fingers around
the moving parts of the seat and armrest:
Putting your hands and fingers around the
moving parts of the seat and armrest is
dangerous as they could get injured.
CAUTION

Be careful not to apply excessive force to
the armrest such as by sitting on it.
Otherwise, it could be deformed or
damaged.
When storing the armrest, return the cup
holder to its original position. If the
armrest is stored without returning the
cup holder to its original position, the
cup holder could be deformed or
damaged.
